The method specifically comprises the following steps: the system comprises a warehouse partition unit 1, a warehouse partition unit 2, a route layout unit 3, a laser navigation forklift 4, a laser alignment unit 5, a vision acquisition system 6 and a control system 7.
The warehouse partitioning unit 1 is used for partitioning the whole warehouse into a plurality of stock areas for storing gypsum boards with different specifications, the stock area partitioning unit 2 is used for uniformly partitioning each stock area into a plurality of stock plots which are uniformly distributed, and the route layout unit 3 is used for setting a main conveying route in each stock plot and setting a plurality of sub-conveying routes in each stock plot.
Warehouse district partition unit 1, warehouse district partition unit 2 and route layout unit 3 are used for dividing the warehouse and store the gypsum board of different specifications respectively, conveniently to the management of gypsum board, and the operation is fairly simple when later stage is delivered from godown.
The laser navigation forklift 4 is used for conveying gypsum boards from a production end to the corresponding stock areas, and all navigation routes from the production end to each stock area are stored in the laser navigation forklift 4.
The carrying steps of the laser navigation forklift 4 in each stock land block are as follows:
firstly, planning all carrying routes from a gypsum board production end to all stock areas, and integrating, packaging and storing all the carrying routes into each laser navigation forklift;
then, defining a laser navigation fork truck group distributed to each inventory area, and setting the laser navigation fork truck group to only call a carrying route from a gypsum board production end to the distributed inventory area;
secondly, setting a plurality of uniformly distributed stocking points on each sub-conveying route according to the distance between the stacking positions of two adjacent gypsum boards on each sub-conveying route;
finally, the laser navigation forklift set stores the gypsum boards at the next stocking point position after the stacking height of the gypsum boards at each stocking point of each stock block reaches the required height.
That is, the laser navigation forklift 4 of the present embodiment conveys gypsum boards to the corresponding stock areas according to the size specification, and when stacking each stock area, all stock points in one stock area are piled up in order, making full use of each stock area, thereby avoiding the problems of insufficient storage and space waste in warehouse applications.
When laser navigation fork truck 4 carries every stock point with the gypsum board from the production end and carries out the gypsum board stack, when the focus of guaranteeing the gypsum board stack is on same vertical line, need utilize laser to aim at unit 5 and carry out the position calibration, when guaranteeing upper gypsum board stack, the both sides limit of upper gypsum board aligns with the both sides limit of lower floor's gypsum board.
The control system 7 is used for correcting the movement of the laser navigation fork truck 4 and the times of pile-chopping of the laser navigation fork truck 4 at each set-off point of the sub-conveying route.
Laser is aimed at unit 5 and is set up laser navigation fork truck's front for calculate the distance between laser navigation fork truck and the preceding fender both sides limit, wherein two the distance between unit 5 is aimed at to the laser is less than the pile length vision collection system 6 of chopping of gypsum board sets up laser navigation fork truck's front is used for acquireing the gypsum board stack image of every putting goods point of sub-delivery route.
The specific working steps of utilizing the laser alignment unit 5 and the vision acquisition system 6 to adjust the position of the laser navigation forklift 4 are as follows:
and the vision acquisition system 6 acquires the picture of the gypsum board at the lowest layer of each stocking point in real time and acquires the edge information at two sides of the gypsum board.
The control system 7 creates a vertical relationship between the horizontal line and the line where the measuring points of the laser alignment unit 5 are located.

2. creating a two-dimensional coordinate system of the output data of the laser alignment unit 5 and the movable fork plate uniform speed lifting time of the laser navigation fork truck 4;
3. counting a time period corresponding to the stable output data of the laser alignment unit 5;
4. and calculating the stacking and chopping height of the gypsum board detected by the laser alignment unit 5 according to the speed and the time period of uniform speed lifting of the movable fork board of the laser navigation fork truck 4.
That is to say, in the stack process of gypsum board, laser alignment unit 5 not only can real-time supervision laser navigation fork truck 4 body apart from the position of the stack gypsum board, can also realize measuring the height of the stack gypsum board simultaneously, according to the specific step that the gypsum board pile chops the number of times of highly calculating the gypsum board of pile chops that laser alignment unit 5 detected is:
setting the height of each layer of gypsum board; and calculating the times of piled and chopped gypsum boards of each stocking point according to the real gypsum board piling and chopping height.
Because when the portable fork board of laser navigation fork truck 4 is in the lowest position, the interval that unit 5 and lowermost layer gypsum board were aimed at to the laser is equipped with the compensation distance, and real gypsum board pile chops the height specifically to the gypsum board pile chops height and compensation distance accumulation that unit 5 detected are aimed at to the laser.
Every put real-time heap of goods point and chop the gypsum board number of times and equal to and add 1 to the gypsum board number of times of having piled up and chop, for example the gypsum board detects 2 layers of gypsum boards of stack, 4 stack work backs of laser navigation fork truck at this moment, the gypsum board number of piles of this putting the goods point stack adds 1 for the gypsum board stack number of piles that has detected, that is to say, the stack number of piles of gypsum board is 3 this moment, in time proofreads and correct with vertical high counting unit 802's count result, the gypsum board stack number of piles that uses laser alignment unit 5 to detect is accurate to the realization is to the calibration work of whole memory space.
The present embodiment can thus realize the following functions by only one laser alignment unit 5:
firstly, the distance between the vertical line of the laser emission point of the current laser navigation forklift and the two side edges of the stacked gypsum board is obtained by using the emission module of the laser alignment unit 5, and the position of the laser navigation forklift is continuously adjusted until the distance between the laser emission point of the laser navigation forklift and the two side edges of the stacked gypsum board is equal.
